Turkey's holiday resort Antalya has become the most popular tourism destination for Germans, according to market researcher GfK. Summer bookings made earlier this year showed Antalya has become the number one choice of German tourists, followed by the Spanish island of Mallorca and the Greek island of Crete, Nuremberg-based GfK said in a new report released ahead of next week's Berlin tourism fair. Sales revenues from Turkey bookings have ballooned 58 percent, showing growing demand among German holidaymakers for beach holidays on Turkey's Aegean and Mediterranean coasts. 'Turkey is celebrating the comeback of the year,' the report said, adding that it expects strong demand to continue in the coming weeks. Turkey aims to attract more than 5.5 million German tourists this year.
